...I know this is really OCD of me. But this scoreboard clock runs 2-3 seconds slower every 24 hours. So after a month, it's one minute behind...ect,ect. Any suggestions on possibly re-calibrating it??? I've already change the battery, no change. Any input would be really appreciated

Yes, but it would be easiest if you had an accurate frequency counter to make sure you hit 32,768.0 hertz. A few minutes per month is not a very larger error and it may be caused by temperature variation - some clocks compensate for temperature and some do not. If yours does not, then it is unlikely that you will ever have an accurate clock (except by random chance some months).
